A locking member (e.g. ball 18) in the apertures (19 and 21) may now be moved upwardly, on pulling of the coupling member (8), to occupy the recess (20) and the aperture (19) so as to allow complete withdrawal of the coupling member (8), e.g. to free a shopping trolley. The coin is released by reversing the procedure on re-insertion of the coupling member (8).

Abstract: A skip to be suspended in a mine shaft has a discharge opening at the lower end region of a chamber defined by a skip body. A door closes the opening and can open to discharge material from the chamber. Door operating members at opposite sides of the body are pivotable about a common axis between a closed position in which the door is closed and an open position in which the door is open. Connectors connect the members and the door and the connectors cross the pivot axis as the door moves between the open and closed positions. The connectors can be at least partly flexible. It is desirable for the chamber to be generally of a greater cross-sectional area at a level above the operating members than at the level of the members and for the body to extend above and at least partly cover the operating members.

Abstract: An apparatus attached to the trailing end of a passenger vehicle that carries a small three wheeled vehicle of the type used by people who have difficulty in walking. Three ramps in triangular array are supported by a support assembly that is raised and lowered by a small motor. The raising and lowering is accomplished by a telescoping member that causes a linkage apparatus to lift the ramp members when the telescoping member is extended and to lower the ramp members when the telescoping member is retracted. The profile of the apparatus is low in that it is positioned below the bottom edge of a station wagon rear door and does not interfere with the opening of that door. A hinge allows folding of the apparatus into a generally vertical plane when not in use.

Abstract: Molded carrier ring-type electrical components are unloaded from a shipping tube by providing the bottom of an escapement mechanism with a substantially flat surface to which the "coin stack" arrangement of components falls during loading of the stack into the escapement. This flat surface presents to the bottom component of the stack an area which is sufficient for preventing dumping of the stack through the escapement and for releveling components which become tilted during loading of the tube into the escapement. The flat surface is biased upwardly by springs and displaceable downwardly against such biasing by a component transfer slide during lateral displacement of the transfer slide to the stack in order to acquire and remove the bottom component from the stack.
